Charging Pakistan with supporting terror modules operating in India, Defence Minister A K Antony on Monday said it was a 'serious' matter and the country will defeat the designs of the destablising forces.

"Militants are getting support from across the border and it is a fact. Already the Home Minister (Shivraj Patil [Images])and others in the government have expressed their opinion on this. It is a matter of serious concern," Antony told media persons in New Delhi [Images] on the sidelines of a seminar by a defence think-tank.

The minister was responding to a query on Pakistan's support to terrorism in India in the wake of the serial blasts in Delhi and other parts of the country.

"Pakistan is in transition to democracy again and we wish that there must be peace and stability (in that country). That is India's wish," Antony said.

On the recent bomb blasts in Delhi, Antony said India has taken the attack seriously and the government was committed to track the forces behind 'the heinous crime'.

On the increased infiltration attempts by militants along the Line of Control [Images] in Jammu and Kashmir [Images], the minister said the recent firing by Pakistan Army [Images] along the LOC was mainly to assist infiltration by militants.

"Indian armed forces are vigilant. By and large, we have been able to defeat the attempts of militants. The coming few months are crucial and we have to be more alert. The armed forces have asked to be more vigilant," he said at the event organised by think-tank CENJOWS.

Army chief General Deepak Kapoor, endorsing the views of the Defence Minister, said infiltration was on the rise.

"Infiltration has increased in the past one-and-half months. As of now normalcy is returning to Jammu and Kashmir, and the militants are trying to destabilise it," he said.

Kapoor said army had foiled an infiltration attempt by militants at Tangdhar sector of J-K on Sunday, killing two ultras.

"We are ready to face any challenge. All attempts to infiltrate will be beaten. We will not allow J&K situation to be disturbed and the degree of normalcy is maintained," he added.
